mechanicus-banner: reorient text from loyalist Mechanicus to Dark Mechanicum

The previous phrasing was canonical-loyalist Adeptus Mechanicus (Lex
Mechanicus, Omnissiah Be Praised, Christian cross ✠, Binary Is Blessed).
Retheming for Chaos-aligned Dark Mechanicum:

Compact banner:
  L E X   M E C H A N I C U S             -> L E X   H E R E T E K
  OMNISSIAH BE PRAISED · DEUS EX MACHINA  -> SCRAPCODE TRIUMPHS · BLOOD-FORGE ETERNAL
  B I N A R Y   I S   B L E S S E D       -> F L E S H   I S   W E A K
  ✠ (Christian cross)                      -> ✴ (eight-pointed Chaos Star)

Full banner left block analogously (LEX HERETEK / SCRAPCODE TRIUMPHS
/ BLOOD-FORGE ETERNAL / Flesh is weak. / The cogitator hungers.).
